Specification of Letters Patent.

Patented Feb. 13, 1906.

Application filed February 9, 1903. Serial N0. 142,574.

To all 11/71/0112 it may concern:

Beit known that I, DEMrsEY S. EDENFIELD, of Savannah, in the county ofOhatham, State of Georgia, have invented certain new and usefulImprovements in I-Iay-Baling Presses, of which the following is acomplete specification, reference being had to the accompanyingdrawings.

The object of my invention is to produce improvements in hay-balingpresses whereby the durability and efficiency of the machine arematerially increased without detracting from the simplicity of thestructure and with out enhancing the expense of construction.

The details of my invention will hereinafter be specified at large andsuccinctly set forth in the appended claims.

In the accompanying drawings, Figure I is a side elevation of mymachine, showing the plunger-bar at the limit of its outward stroke.Fig. II is a top plan view of the subject-matter of Fig. I, the beam orsweep being partly broken away. Fig. III is a central verticallongitudinal section of the press-box of my machine, theplunger-headbeing shown in elevation. Fig. IV is a section on the line IV IV of Fig.III. Fig. V is a top plan view of the plunger-actuatmg mechanism asshown in Fig. II with the beam or sweep cut away.

Referring to the numerals on the drawings, 1 (compare Figs. I and II)indicates one of the side frame-pieces, and 2 the other. They extendsubstantially from end to end of the machine and are united toconstitute a strong and rigid oblong frame at one end by crosspieces 3and at the other by massive blocks at and 5, which are selected ofweight and strength sufficient to afiord suitable bearings for theactuating mechanism of my machine.

The cross-pieces 3 (see Fig. IV) support the floor 6 of the press-box,which is defined by side pieces 8' and 9, supported, respectively, byuprights 10 and 11, whose lower extremities are bolted orotherwisesecured to the side pieces 1 and 2, respectively. The pressboxis completed by an upper wall 14., which extends above a portion only ofthe floor 6, the remaining portion of the distance being left open toconstitute a feed-opening 15. (Compare Figs. II and III.) The rearwardends of the sides 8 and 9 of the press-box are provided with oblongopenings 16 (one of which is shown in Fig. I) in order to afford freeaccess to the bale while in the box.

17 indicates bolts which secure the upper ends of each pair of uprights,respectively, together.

Each of the sides of the box (compare Figs. III and IV) is provided witha pair of metal lic strips 19 and 20, which, extending from the forwarduprights 10 and 11, respectively, project beyond the rearward uprightsand support tail-frame side pieces 21, parallehto the rearward uprights,that are secured at their opposite ends, respectively, by transversebolts 22 and 23. The strips 19 and 20, being of metal, possess suchdegree of flexibility and resiliency as to permit the side pieces 21 tobe drawn toward each other or squeezed, as it is termed in the art,under tension of the bolts 22 and 23 without deflec tion of the sidepieces of the frame proper of the machine, which is preferably of rigidconstruction.

25 indicates a plunger-head which, working in the forward end of thepress-box, is adapted to force material fed in through the opening 15into the completely-inclosed end or compressing compartment of thepressboX. Owing to the elastic character of the material. intended to bebaled in my press, I provide in each of the side pieces 8 and 9 oblongrecesses 26, within which work the bent ends 27 of spring-dogs 28, whichbeing confined (see Fig. IV) at their opposite ends between the forwarduprights of the press-box and the side pieces 8 and 9 thereofrespectively tend by their resiliency to keep their bent ends 27inserted through the recesses 26. By this means material that is pushedbeyond the ends 27 of the spring-dogs is kept partially confined by themwithin the press-box, so that the space underneath the opening 15 iskept unobstructed, ready for the reception of additional material to befed into the bale.

The dogs 28 are made resilient in order to oppose minimum resistance tothe passing by them of the material to be baled; but I prefer that theplunger-head 25 should pass and repass them without engaging them andfor that reason provide in the opposite sides of the plunger-head and inalinement with the respective bent ends of the dogs open andunobstructive lateral recesses 29. (Compare Figs. III and IV.)

The plunger-head is provided with a plunger-bar 30, whose movement islimited to true longitudinal reciprocation and which terminates in adeflected tailpiece 31, (see Fig. II,) the parts 30 and 31 preferablyconsisting of separate timbers united, as by bolts 31. The purpose ofthe deflection of the tailpiece will be explained farther on.

The plungerhead is by preference yieldingly held in a normal position,which maybe designated its retracted position-that is to say, in theposition shown in the drawings.in which it is retracted to the limit ofits forward movement, in which the opening 15 is perfectly free andunobstructed. For maintaining the normal position of the plunger-head asdescribed I prefer to employ a coiled spring 32, secured at one end, asindicated at 33, to the bottom of the plunger-bar and at the other, asindicated at 34, to the block 5.

35 indicates a stop-piece which impinges against the block 4 and whichis preferably secured to the bottom of the plunger-bar.

The tailpiece 31 is provided upon one side with arack 37 and upontheother side with a wearing-plate 38. The wearing-plate bears againstan antifriction-roller 39, pivot- I ally mounted upon a bolt 40, whichpasses through the blocks 4 and 5, while the rack 37 is designed toengage at intervals the geared segments 41 and 42 of a horizontaldrivingwheel 43. I prefer that the wheel 43 should, with its gearedsegments, constitute a perfect gear except for the two oppositemutilations which separate the two geared segments 41 and 42. I mentionthis feature especially because by the employment of a regular mutilatedgear'I secure a distinct gain in power over machines of the class towhich my invention belongs in which plunger-actuating members ofirregular shape are employed.

The wheel 43 is preferably made integral with a journal 45 ofcomparatively large diameter, which is carried in a suitable bearing inthe blocks 4 and 5 and for whose accommodation the massiveness of saidblocks is provided. The journal 45 is carried within the frame of themachine between the side frame-pieces 1 and 2, and by reason of thislocation the efficiency of the machine is augmented. It is toaccommodate the location of the journal 45 above referred to that thetailpiece 31 of the plunger-bar is deflected, as has already beenspecified. The relative locations of the tailpiece 31 and of the journal45, through the engagement between the rack 37 of the tailpiece and thegeared segments of the driving-wheel 43, dispose the driving forcederived from the actuating member in a direct true line substantiallycoincident with the longitudinal axis of the plunger-bar 30, whosemovement is, as has been specified, limited to a true horizontalreciprocation.

The beam or sweep 46 is secured, as by bolts 47, directly against thetop face of the wheel 43, and by that means the shaft connection betweenthe sweep and the plunger.-

crossing the plunger-bar and frame of the v machine. This I accomplishby locating the sweep transversely between the geared seg-- ments 41 and42, and it should be observed in this connection and upon reference toFig. II that the sweep in that figure is shown in the position which itoccupies immediately preceding the engagement of the teeth of the wheel43 and of the rack 37 for imparting driving motion to the plunger-baragainst the tension of the spring 32. Before the sweep can be broughtinto alinement with the plunger-bar that member will have commenced itstravel; but its movement in the first place meets with slightresistance. It is only when the material ahead of the plunger 25 isdriven with force upon that accumulated by previous operations of theplunger .within the press-box that the real work of the plunger begins.By that time the animal hitched to the sweep and pulling in advance ofit will have cleared the frame of the machine, where it intercepts hiscircle of travel. It may be further observed that although theplungerbar 30 makes two double reciprocations with each completerevolution of the sweep 46 it is only with respect to the meansofieffecting one driving movement of the plunger-bar that provision mustbe made for relieving the strain upon the animal, because While theother corresponding movement .of the plunger-bar is being made theanimal is traveling the free and unobstructed portion of his circuit.

It is believed that the operation of my machine will be obvious from theforegoing specification to one skilled in the art Without furtherdescription and that in an instrument addressed to one so skilled nospecial reference to the well-known manner of sepa- IIO rating, tying,and ejecting the bales from the pressbox is necessary.

What I claim is 1. In a baling-press, the combination with aplunger-head and its actuating mechanism, of a press-box frame providedwith flexible resilient metallic strips upon its respective sides,tail-frame side pieces carried by the the box, and means for drawing thepieces toward each other against the resistance of the resiliency of thestrips.

3. In a baling-press, the combination with a plunger-head, its actuatingmechanism, and a press-box frame provided with side pieces and aplurality of pairs of oppositely disposed uprights, of flexibleresilient metallic strips upon opposite sides of the press-box frame andsecured respectively to the forward uprights and projecting beyond therearward uprights, tail-frame side pieces carried by the projecting endsof said strips respectively in the rear of the box, and means fordrawing the tail-frame side pieces toward each other.

In testimony of all which I have hereunto subscribed my name.
